Sprockets for Harsh Environment Flat-Edge Roller Chain
The teeth on these sprockets are sized to fit Harsh Environment Flat-Edge Roller Chain. To avoid interfering with material conveyed on your chain, the teeth are short and won’t stick out above the chain. For a custom fit on your shaft, machine these sprockets to your exact specifications. They come machined to the shaft diameter listed and are machinable up to the maximum shaft diameter size.

Harsh Environment Flat-Edge Roller Chain and Links
 Chain |  Connecting Link |  Adding Link |
 Adding-and-Connecting Link |  |
With wide gaps between each side plate, debris in dirty environments falls through this chain instead of building up. Originally designed for use in lumber mills and agricultural applications, its wide spacing and heat-treated steel material makes it a good choice for harsh environments. The flat edges create a level surface, so items riding on manufacturing and packaging lines won’t get caught in divots the way they do on standard roller chain. Use with sprockets for harsh environments.
Connecting links are also known as master links. They're used to join the ends of a chain length. The side plate is easy to remove for attaching to a chain. Adding links are also known as roller links. They require two connecting links to join to your chain. Adding-and-connecting links are also known as half links and offset links. A combination of connecting and adding links, they join chain that requires an odd number of links.
